Filed: 1947-01-27
Abstract: 620,816. Sewing. ALDERMAN, P., and COSTELLO, M. J. Jan. 27, 1947, Nos. 2509 and 12810. [Class 112] In a needle-threader the movement of the needle moves a pivoted member to pass a loop of thread through the needle eye and the loop is thereafter held so that removal of the needle completes the threading operation. As the needle is inserted into a channel 15 it is twisted into an aligned position by springs and as it advances it engages a groove 21 in the pivoted member 18 which is pressed by a spring 23. Further advance of the needle causes a hook 22 on the member to project through the needle eye. When the member reaches the position shown in Fig. 5 the thread 27 is inserted into a slot 13 and the needle is removed the hook pulling a loop of thread through the eye. The threader comprises two complementary parts having a slot extending from the channel to the periphery to allow removal of the device from the thread when it is attached to a garment. In a modification (Figs. 9 - 13, not shown) the hook is replaced by a forked bar and the thread is inserted first. On insertion of the needle the'bar pushes a loop of thread through the eye and during withdrawal of the needle the loop is held by a spring attached to the body of the threader.

The storage bay 13 has two channel section boundary walls 15, 16 which act as guides for a pressure plate 65 adapted to overlie the stack. The fingers 29 are carried by the longitudinal side members 26, 27 of a carriage 25 which runs on rails 23, 24 beneath the bay 13. A conveyer 40 is positioned beneath the carriage 25 and is carried by a lifting platform 45 which runs on rails 48. The barrels are pushed on to the conveyer 40, from an infeed conveyer 52, by a pusher 56, the leading barrel engaging an adjustable abutment 60 so that the fingers 29 are positioned above the spaces between adjacent barrels on the conveyer 40. The table 45 is then raised to place the row in the bay 13, and the carriage 25 is moved by a ram 28 to place the fingers 29 beneath the barrels. When the next row is formed on the conveyer 40, the abutment 60 is adjusted to offset this row from the previous row. For unstacking, the conveyer 40 is raised to lift the lowermost row off the fingers 29, the carriage 25 then being moved to place the fingers between the barrels of the row so that, when the conveyer 40 is lowered, the lowermost row is lowered from the bay 13 but the next row engages the fingers 29. The detached barrels are fed to an outfeed conveyer 53. The fingers 29 may be replaced by pivotal clamping jaws (31, Figs. 6 and 7) adapted to engage the lower portions of the sides of the barrels. These jaws may be provided with suction cups. Several bays may be arranged one behind the other, the end bays being closed by vertical wall plates, and a cover plate being secured to the tops of the bays.

Abstract: 763,815. Springs &c. INTERNATIONAL BUSINESS MACHINES' CORPORATION. Jan. 28, 1955 [Feb. 1, 1954], No. 2612/55. Class 108(3). [Also in Groups XXXIV and XXXVIII] A gas-stabilized head for recording apparatus or the like, has a working face 18 with one or more orifices 19 bounded by convex walls 20 diverging towards the face 18 and each containing a divertor 21 having a surface substantially congruent with that of the orifice, and means for so moving each divertor within its orifice that each divertor and orifice define an adjustable nozzle 17 for delivering gas between the face 18 and a co-operating surface of a record carrier 33 or the like in a direction substantially parallel to the surface. As shown, the moving means comprises a screw-threaded connection between the divertor end 23 and the top 25 of the cylindrical head, the latter containing a circular manifold 11 into which air is fed at a pressure greater than that of the ambient atmosphere, and the air exhausting through the nozzle spaces the head away from the carrier 33 e.g. a magnetic tape, drum or disc by a distance determined by the adjustment of the divertor. Due to the divertor 21 diverting the air through substantially 90 degrees, the force arising from the air impinging directly on the carrier and urging the head and carrier apart is reduced, while the Bernouilli effect, i.e. the drawing together of the latter two parts due to the high air velocity and therefore low air pressure therebetween is increased. In the lower surface of the head is a magnetic transducer 27 comprising a winding 28 and a core 29 having a read-write gap 30 the whole being embedded in a disc 30a of non-magnetic plastic material.
